    • We have also considered the possibility that this shift has a charging component. We do not believe that this is a factor here, given that the samples were analyzed in a conducting graphite matrix and that when a flood gun was used, changes to lower BE values did not occur

    • There is a difference in the Au/S stoichiometry in 3D SAMs (2:1) cf. 2D SAMs (3:1). A combination of 3:1, 2:1, and 1:1 Au-S binding is necessary to fulfill the range of Au/S ratios (1.55-1.87) calculated by Luedtke et al. (J. Phys. Chem. 1996, 100, 13324-13329). The XPS experiments reported here cannot, however, resolve these different binding combinations.

    • 1/2 splitting, the Siegbahn LFER for sulfur describes a relationship where BE = 4.75q + 163.03 eV, (r = 0.9733), where q is the net charge on the S. This LFER is based on organosulfur compounds.
